CAGE Fon PICKLING-VATS.

Speceaton of Letters Patent.

Patented Dec. 11, 1906.

Application filed September 6, 1906. Serial No.l333.477.

To all whowt it may concern:

' Be it known that I, RICHARD RIoHAItDs, a citizen of the United States of America, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Cages for Pickling-Vats, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to cages for transferring tin plates from the pickling-vat to the bosh or water-t ank.

The work of removing tin plates from the pickling-vats to the bosh is now done by hand; and the primary object of the present invention is to provide a cage or holder adapted to receive the plates of tin and support the same within the pickling-vat, after which the cage or holder and its contents are raised bodily out of the vat and transferred ,to the bosh. The bottom of the cage is so constructed as to permit it to open to free the cage from its load, leaving the latter within the bosh and allowing the cage to be withdrawn, after which its bottom sections are closed to receive another load.

The construction of the improvement will be more fully described hereinafter in connection with the accompanying drawings, which form a part of this specification.

ln the drawings, Figure 1 is a view in perspective of a cage embodying the invention. Fig. 2 is a detail of the means employed for turning the rods which support the tilting arms. Fig. 3 is an end elevation of the cage. Fig. 4 is a detail side elevation of one of the tilting arms. Fig. 5 is a detail perspective of a movable guard adapted to be applied to the sides of the cage. Fig. 6 is a top plan of another form of guard extending across the ends of the cage, and Fig. 7 is a detail perspective view of one of the necktie-catches employed to support the free ends of the tilt ing arms.

The reference-numeral 1 designates a rectangular frame the ends of which are connected by a central longitudinal bar 2 and parallel bars 3 and 4, arranged centrally between the bar 2 and the sides of the frame 1.

Depending from each corner of the frame 1 is a post 5, the upper ends 6 of which are threaded and extend through openings in the frame, being secured by nuts 7.

Depending centrally from each end of the frame 1 is a plate 8, each of which is formed adjacent to its lower end with bearings to receive the ends of parallel rock-shafts 9 and 10, said shafts being also supported in bearings formed in the diverging ends 11 of rods 1)2, secured at their upper ends to the central From each of the sides of the frame 1 depend two rods 13, formed at their lower ends with eyes or bearings 14 for rock-shafts 15 and 16, the ends of said shafts being supported in bearings formed in the lower ends of the corner-posts 5.

Upon each of the rock-shafts 9, 10, 15, and 16 are keyed a plurality of tilting arms 17, four being here shown on each shaft. These arms are each formed with an opening 18 for the passage of the rock-shafts and a key-seat 19 (see Fig. 4) to adapt them to be fixed upon said shafts. The arms 17 are oppositely disposed in pairs which aline longitudinally, the arms 17 on the shaft' 16 being opposite those on the shaft 10, while the tilting arms 17 on the shaft 15 are opposite those on' the shaft 9 the free ends of each pair being adjacent to each other to adapt them to be supported by a single fastener or support.

A series of rods 2() are suspended from the longitudinal bars 3 and 4 and from the end bars of the frame 1 in such a manner as to permitsaid rods to be turned radially a quarter-revolution, and upon the lower lend of each of said rods is carried a catch or fastener adaptedto detachably engage the free ends of the tilting arms. I have shown this fastener inthe form of a necktie-catch button 21, each formed on its upper side at each end with an upwardly-projecting oppositely-beveled lug 22, said lugs being adapted to enter correspondingly-beveled recesses 23 on the under sides of the free ends of the tilting arms 17.

Each of the rods 20 is provided near its lower end with a collar 24, provided with a depending lug adapted to enter a slot 25, formed in the upper surface of the free end of each of the tilting arms to prevent lateral play of said arms.

It is necessary to provide means for turning the rods 20 a suflici'ent distance to disengage the catches 21 from the ends of the tilting arms, and for this purpose I provide IOO y `:sets in all Ifor Athe 'cage fhere shown.

.27 to receive pins 28, depending from the rod 29, the latter projecting at one end of the cage and being provided with a handle 30.

Two of the rods 29 are shown, one controlling the rods 20, depending below the bar 3, and the other the rods depending below the bar 4.

When 'the necktie-catches are -in the position shown in Fig. 1, the free ends of the arms 17 are in the horizontal position shown to support the tin plates which rest thereon on `their edges. When the rods 2O areturned'by vpulling uponthe lrods 29, the catches 21. are turned a quarter of a revolution, which perrmits the arms to dro to the position shown vbyidotted lines in Fig. 3, thus releasing vthe vvcage from its load and allowing` the cage to be withdrawn. The tilting armsil? must be returned to their `'horizontal `position in readirvnessto receive anotherload, -and'this may be accomplished yby any desired mechanism, that here shown comprising 'rods 3l, connected by links 32 to said arms, ythe upper ends of the rods being connected to vchains .33, assing over guide-pulleys 34. Two sets o'f t ese arm-retracting devices are required for each series of pairs of'tilting armsorfour The chains 33 are fpreferably :connected at the `centerrof the vend of the cage to a pull-ring 35, so -thatfall of the tilting'arms 'may beretracted at the same time.

Each of -pthe-corner-posts 5 is circumferentiallyrreduced to form an annular shoulder 36, upon which are loosely `supported the .l ends 37 of guards 38,said ends-being formed vwith openings rthrough which the upper reduced portions ofthe postseXt-end. These guards eXtendacross the ends of the cage to iretain thertin plates inposition.

, Removable -guards 39, :having their=ends 40recessed 'to iit-thedepending'rods, maybe employed ,to partiallyT close the sides of the Lcage-or to separate the stacks of plates withain-thev cage. Oneof theseguards 39is shown :in-Eig. 1. They are supported upon'pins 41,

p yp1"o,]ecting from the Yvertical rods, and may be arranged at different heights with rela- .tion-tothe sizeoftheplates'to'be'treated- The utility and operation-ofthe improve- .ment will be :readily understood. The en- 'tirevcage is ladapted `tofloe suspended yby suitable means (not shown) and after being ifilled with 4tin plates is lowered into the pickling-vat After remaining 4therein .for the required rtime the cage and itscontents are xraisedout of the vat and'transferred to the bosh,'the iioor ofwhich is,provided with parallel cleats, upon which the 'lower edges of the tinplatesrest. The arms `17 are then released by the means described for'that purpose, after which the emptylcage is -raised -out ofthe bosh, and the'arms -17 are retracted, as already explained, and secured to the vcatches 20, ready for relling.

Bars 24a, formed with openings for they rods 20, rest on the collars 24 to keep said rods in alinement. The rods 2O are also threaded at their upper ends to receive nuts 24h.

I would have it understood that the invention is not restricted to the details of the mechanism shown, but includes all such modifications and changes in the form and construction of the mechanism as vmay be resorted to without departing from the spirit and scope of the invention as set forth and defined in the following claims.
